PCB联盟网-科普知识--《电子封装材料与工艺》 学习笔记 54页本人主要从事 IC 封装化学材料(电子胶水)工作,为更好的理解 IC 封装产业的动态和技术,自学了《电子封装材料 与工艺》,貌似一本不错的教材,在此总结出一些个人的学习笔记和大家分享。此笔记原发在本人的“电子中,有兴趣的朋友可以前去查看一起探讨第一章 集成电路芯片的发展与制造 1、原子结构:原子是由高度密集的质子和中子组成的原子核以及围绕它在一定轨道(或能级)上旋 转的荷负电的电子组成(Neils Bohr 于 1913 年提出)。当原子彼此靠近时,它们之间发生交互作用 的形成所谓的化学键,化学键可以分成离子键、共价键、分子键、氢键或金属键; 2、真空管(电子管): a.真空管问世于 1883 年 Edison(爱迪生)发明白炽灯时,1903 年英格兰的 J.A.Fleming 发现了真 空管类似极管的作用。在爱迪生的真空管里,灯丝为阴极、金属板为阳极; b.当电子管含有两个电极(阳极和阴极)时,这种电路被称为二极管,1906 年美国发明家 Lee DeForest 在阴极和阳极之间加入了一个栅极(一个精细的金属丝网),此为最早的三极管,另外更 多的电极如以致栅极和帘栅极也可以密封在电子管中,以扩大电子管的功能; c.真空管尽管广泛应用于工业已有半个多世纪,但是有很多缺点,包括体积大,产生的热量大、容 易烧坏而需要频繁地更换,固态器件的进展消除了真空管的缺点,真空管开始从许多电子产品的使 用中退出; 3、半导体理论: a.在 IC 芯片制造中使用的典型半导体材料有元素半导体硅、鍺、硒,半导体化合物有砷化镓(GaAs)、 磷砷化镓(GaAsP)、磷化铟(InP); b.二极管(一个 p-n 结),当结上为正向偏压时可以导通电流,当反向偏压时则电流停止; c.结型双极晶体管:把两个或两个以上的 p-n 结组合成一个器件,导致了之!

本文大致可划分为四大部分。首先简单探讨LED,其次重点论述LED封装技术,然后简单介绍LED相关术语、LED相关工具,最后总结。经过对大量文献的阅读分析论证,LED封装技术主要涉及到封装设计、封装材料、封装设备、封装过程、封装工艺五大方面。封装设计是先导,封装材料是基础,封装设备是关键,封装过程是支柱,封装工艺是核心。封装过程大致可分为固品、焊线、灌胶、测试、分光五个阶段。封装工艺,主要体现为生产过程中的各个阶段各个环节各个步骤的技术要领和注意事项,在LED封装生产中至关重要,否则即使芯片质量好、辅材匹配好、设备精度高、封装设计优,若工艺不正确或品控不严格,最终也会影响LED封装产品的合格率、可靠性、热学特性及光学特性等。总之,合格的工艺能保证LED器件的质量,改进的工艺能降低LED器件的成本,先进的工艺能提高LED器件的性能。因此,本文重点在于对LED封装工艺进行分析和综合,简单介绍了封装设计,封装材料、封装设备、封装过程,详细地说明了封装工艺,总结了LED封装工艺的技术要领、注意事项,明确了LED封装有哪些工序、流程、制程、过程、环节,每个工序用什么材料,材料怎么检查怎么仓储怎么使用,用什么工具,工具怎么使用,操作步骤顺序和方法是怎样的,操作中要注意哪些事项,执行要达到什么标准,还分析了死灯的原因,介绍了LED封装生产过程中的静电防护措施。
